Test condition is I
Detection accuracy of the update algorithm for the falling edge of the signature region is highly dependent upon specific target geometry. Please consult
The repeatability specification is based on statistical evaluation of a sample population.
Upper limit is I
Power-on speed ≤ 200 rpm. Refer to the Device Description section for information on start-up behavior.
Detection accuracy of the update algorithm for the first rising mechanical edge following a signature region can be adversely affected by the magnetic
